Default Onan 6.5 NH 3CR 16004p Air Cleaner

Mine has the factory low profile plastic air channel (140-153). Which is just fine for the designed purpose. I bought this on a trailer and am planning on using it for temp power while I build my home. The air system as designed is just laughable for my purpose. Does anyone make a air cleaner which can or does adapt to the carb directly. My carb has the 140-1492 adaptor on it and a manual choke. The choke flap has no screw hole in it so I am going to have to clamp from the outside of the carb. I do have the breather tube so that will be incorporated.
Surely someone has crossed this bridge and there is a made solution. The plastic housing will not last in southern Arizona even in the winter.

Comments and suggestions appreciated.

A day and a half beating my head against the key board. I found a VW, EMPI brand paper air cleaner. Fits the two inch neck of the carb and has a nipple for the breather tube. Less than $30 delivered.

One of those things that I never figured to be so hard.

I have the carb plate and the OEM air ducting available if any one is keeping their machine OEM. The plastic ducting has paint on it from some rattle can and holding it up seems bent to me. I surmise some adjusting will be required.
